STB/F0i
Data Strobe/Frame Pulse (Input).
For SSI mode this input determines the 8 bit timeslot
used by the device for both transmit and receive data. This active high signal has a
repetition rate of 8 kHz. Standard frame pulse definitions apply in ST-BUS mode. CMOS
level compatible input.
17
CLOCKin
Clock Input.
The clock provided to this input is used by the internal phone functions. In ST-
BUS mode this is the C4i input. In SSI synchronous mode, this is the Bit Clock input. In
SSI-asynchronous mode this is an asynchronous 4 MHz Master Clock input.
18
XSTL2
Crystal Input (4.096 MHz).
Used in conjunction with the CLOCKin pin to provide the master
clock signal via external crystal.
19
V
DD
Positive Power Supply (Input).
Nominally 5 volts.
20
HSPKR-
Inverting Handset Speaker (Output).
Output to the handset speaker (balanced).
21
HSPKR+
Non-Inverting Handset Speaker (Output).
Output to the handset speaker (balanced).
22
SPKR-
Inverting Speaker (Output).
Output to the speakerphone speaker (balanced).
23
SPKR+
Non-Inverting Speaker (Output).
Output to the speakerphone speaker (balanced).
24
V
SS
SPKR
Power Supply Rail for Speaker Driver.
Nominally 0 Volts.
AUX
out
Auxiliary Port (Output).
Access point to the D/A (analog) signals of the receive path as
well as to the various analog inputs.
25
26
AUX
in
Auxiliary Port (Input).
An analog signal may be fed to the filter/codec transmit section and
various loopback paths via this pin. No external anti-aliasing is required.
27
MIC+
Non-inverting on-hook answer back Microphone (Input).
Microphone amplifier non-
inverting input pin.
28
V
SSA
Analog Ground (Input).
Nominally 0 V.
